Just found this channel, love it. I'm an old retired mechanic from England. I did my apprenticeship with Jaguar. Quick funny story. I'd gone through college had all my study work in a box and my first day at Jaguar the mechanic or specialist took it all and chucked it to one side and gave me a 10ml spanner. That's what you need to be a mechanic he said and look after it because you will always be searching for one. He wasn't wrong. New subscriber. Regards from London.
Just as Steph said it, I was literally thinking "Juan is super legit, just down to earth and knows his stuff". Not a traditional screen personality but really interesting to listen to.
@@AlecCarlsonI don’t really agree, propagate would be more like a crack growing/spreading. It usually notes growth. Migrate is usually referring to movement of something like a fluid or electrical current. Migrate is the right word, propagate better than mitigate for sure. Coming from an engineer who has had to give depositions on this stuff in the never ending battle of owner vs contractor disputes. 🤢
I was really into air cooled VWs in the ‘80s and got a job at a VW/Porsche shop. One day I was told to replace the water pump on a 928, so I looked in the book… “9.5hrs” and about 20 minutes of it was actually replacing the, timing belt driven, water pump.
In engineering class here in Germany our Professor always told us of the German tractor company Lenz. They've built tractors that needed no maintenance and would run forever. The hot bulp engines could be operated by an illetarete peasant and ran on everything from lard to heavy fuel oil. They sold them until everyone who could afford one had one. And then they went bankrupt. The more complex a car is the more expensive it is to fix, those cars must survive nor more 10 years or 250.000 km, leave a good impression and then fail. It's a sad reality.
@@tienming6174 If you're interested in hot bulp engines I'd recommend you google them, but they're no longer in use since they have a very low compression and therefore low efficiency.
Yea I mean it's just basic business... if you make something that lasts forever you're eliminating tons of future customers and you're now forced to compete with yourself to stay alive.
So, I'd like to explain something - coming from an engineer. We don't want to design stuff that makes it hard to work on. We are made to by others. I'm a process electrical engineer, which means I design the automation systems in manufacturing facilities. I'd love to make every control panel have lots of room for technicians to work in, because that makes it easier on me for design and implementation as well. But what happens is the higher ups say - well, cost of 50 48" panels is xxx more than 50 36" panels, so just slam everything into those smaller panels. Or We need x (which usually takes up 12" of space with room to wire/access) to fit in this 8" space, and no we can't change anything else because there's no room, just make it fit. That is the reason you get those bolts in odd places that are hard to reach, or those terminal blocks with only 1/2" of finger room to wire them and so on. We don't want to make stuff that way, but we don't usually have the final say. Everyone blames the engineer, trust us, we know, we told the project managers and higher ups about it but were told to do it anyways because they don't care.
yup I'm a mechanic and I defend yall all the time... I know you guys are way too smart to not notice obvious serviceability issues during the design process, it's the pencil pushers always trying to save a buck making yall look bad especially in the Auto Industry. It has gotten so bad I have literally seen repair instructions written by BMW that call for you to cut away pieces of plastic or just straight up break trim pieces to repair something else 🤣🤣🤣 I know for a fact no engineer would willingly sign off on that
Hit a pothole in my Honda accord when I was 17. It broke the cv axle, upper and lower control arm, and the strut. Pothole was big enough that the wheel dropped in and everything slammed into the asphalt. My brother and I fixed it and got to learn the dangers of a spring when it goes flying around the garage 😂
I hit a 10cm deep pothole once at 80km/k. broke only the rim, but I was like... soo far away, and broke, I had to drive the car back, and just shred the tire, cuz the rim was already bent and cracked. how that car did 15km of just rim drive, I will never know
Steph quickly is becoming a favorite of mine! She fits in perfectly with Angie and Sandro. Juan also is really cool, I really enjoy his more calm, but still really knowledgeable style.
The mono wiper on the older MBs in AMAZING. I'm akways in awe how much of the window it actually reaches, arguably more than the more common dual wiper setups. And I'm positively surprised that it does not seem to break. Very well designed mechanism inside of this "turtle shell" it sits in.
I love them too, I have a couple W202's that have them. The only real maintenance they require is to be re-greased which isn't hard by any means. The bigger issue is the wiper motor has a worm screw that rotates a plastic shaft, which will make the wiper "pause" in the middle of the window when it starts to fail. Although considering the cars are well over 20 years old, I wouldn't say it's a "big" issue if they are just starting to fail. Just replace them with OEM, a cheap aftermarket failed on me within a couple of months.
I had to rebuild one because of parts availability. I watched a UA-cam video and got what new parts we could but it worked in the end. Pretty cool system and a learning experience
My Father still uses daily his '99 E220 CDi (auto) , that wiper arm never gave any problem . My 2 Citroen BX also have a monoarm , but no need for the cinematic mechanism has the windshield in high enough , but the sprayers are in the arm and move with the blade (the tube passes in the middle of the axe of the Arm ) , so it never runs dry , and you don't have the sprinklers on the hood for aesthetics .
Bruh I love these two. Everyone that has shown up on Real Mechanics have really been gems and have provided me with valuable knowledge and I appreciate all of you helping me grow.
16:53 What happens is that oils have extremely high surface tension. They are engineered this way to get into small places and cling to and coat the wear surfaces. Pretty much every wire in a car is stranded wire, there are almost zero solid core wires ever found in a car. Once the oil gets into a connector it will cling to all the individual strands inside the wire. Because of the very high surface tension it literally will be sucked along by capillary forces through that tiny space between all the strands. The capillary action will just continue to flow that oil drop by drop through the wires until they find something they cannot get around (a computer, connector, etc) and sometimes even drip out onto other electrical components. Any places that are really hot it'll turn into a gummy shellac like coating. And as most wiring gaskets are not made from oil safe materials the solvents that remove carbon buildup from the engine will actually start to dissolve components in the plastics making them very brittle and seals fail.
@@mattbritton6222 So it impacts them in a few ways: One engine motor oil has solvents and detergents in it. Now not all components will have issues with this, but capacitors are usually pretty vulnerable to being comprised by engine oil. There are capacitors that do not have just a thin seal, but they cost more, so the cheap ones are typically whats found. Once oil wicks into them they loose their ability to function within spec. Two, it will eat away certain seals and can damage masking on boards. This can lead to water entering past those seals and causing more problems. Masking issues will cause potential shorts in the layers on a PCB. Three, clean oil is not much of a problem for electrically, its usually not conductive. However dirty oil is. A lot of impurities in old engine oil make is mildly conductive. So while its rare to directly cause shorts, it can introduce a general capacitance and screw up higher speed digital signals. Four, Oil can tend to turn into a thick paste that impedes airflow so systems like the ECU that may need good cooling might just cook themselves when coated with oil residue. To be honest if you had a high quality petroleum oil without the additives (e.g. Mineral Oil) it would generally be fine to submerge all your electrical components in it. It's really just that things designed to remove carbon build up from engines also are not great for electronics.
I wonder why this is more common on German vehicles? I mean, I've had have valve cover gasket leaks on every GM vehicle I've ever owned, not fast (like enough to keep things visibly oily and greasy but not quite drip on the ground). I bothered to measure it on one vehicle I had and found it was 1/4 of a quart per 10,000 miles... which is low, but over many miles it adds up to multiple quarts run out over the bottom half of that engine, it was quite greasy on all these vehicles. I'm just saying if it wsa guaranteed that oil worked it's way up, I think I would have been screwed on all these vehicles. My Chevy Cruze started really pissing out oil, I fixed an oil line myself, then got the valve cover and valve cover gasket replaced when they started leaking like a sieve (it began leaking fast enough I brought a jug of oil with me and was topping it up every time I stopped. No I didn't let it run low, and I got it fixed ASAP but the shop was booked up so that took about a week.) I replaced the parts on these that all act up at about 140,000 miles so it's been running nice and holding it's fluids in fine since. Anyway, with all that oil dumping out I didn't have it run up my wiring on there either.
That commercial w Bob Hall was great. Having the guests be a part of the ads and play the corresponding ad scene with the guests that are on that same episode would be a great addition.
Well that begs the question, was this video sponsored by SimpliSafe or was SimpliSafe a cover for the real sponsor, The Miata (not Mazda in general just specifically the Miata models and anything affiliated with Bob Hall's legacy?) Besides was that really a "bad" thing? I feel like that'd be quite a story to tell anywhere. "What, you were stuck on the ISS due to Boeing's screw up? Ha, that's nothing. Bob Hall kept stealing my food for months."
I saw that glass scratch issue once. Found the problem pretty quick, the customer had "fixed" their door previously(they'd unscrewed the plate for the interior door handle to fix a hook). Trouble is, when they put it back together, they just used whatever screw they had lying around that fit. And they used one that was WAY too long. And then they were surprised when it scratched up their window.
I will give props to the guy for the simple test. I mean most people would do just what his first notion was. "No noise, no problem." Now we just wait for 5 minute crafts to put out some "life hack" ripping this off in a pointless way.
They were better off with no screw. I don't think I have screws on either front door handle of my car, never had a problem! I've taken them off so many times, I don't have any screws, just a hundred pack of the plastic clips, lol. Car audio and sound deadening are the reasons I frequently remove the doors. Pushing diminishing returns to the max! Lol
@@edew9180 There was a time when cars didn't just have one screw on the latch, used to be multiple because the latch plate was an entirely separate assembly. Big chunk of pot metal in the middle of the door panel.
16:33 Propagate, not mitigate. This is capillary action, where a fluid creeps along, even against gravity. The quick fix is filling the harness with oil resistant silicone or RTV at the connecter that fails. The Golf Mk4 has the same issue with the harness from the water temp sensor on the expansion tank. Starts to leak, coolant seeps through the harness into the computer and fries it.
@@mattbritton6222 Any fluid getting into an electrical system will cause issues. It either gets in between connections (breaking the connection), traps heat and overheat the components, or cause other issues. Computer parts are very sensitive and delicate. Even if a fluid is not conductive, it will cause major problems.
10:20 You misunderstand, you don't need the car to take the picture, you need to join a conference call hands free while stuck in traffic. My former CEO used this function all the time.
The last clip, that W124 mono wiper I LOVE IT ..Nothing to laugh about that , it's super well engineered , works fantastic, saves money (one blade to change) ..but you have to service it once at 10 years otherwise the gears inside will crumble like in my case, grease gets dried out and boom, they crack creating a mess , $100 in parts and a 3 hours job to repair it. People don't service anything nowadays, cars are consumables and if they last 100k miles , all good , next one..W124 lasts 500 k miles with very little love
I am German and I agree. I drove an Audi and you had to bring the car to the mechanics to change a light bulb in your head lights, that is really frustrating. Or a 5 cent light bulb in your dash breaks and you would have to remove the middle console and the dash to change it, that is simply a stupid design. Looks great though, but as soon as you start repairing stuff, it becomes a nightmare. Imagine the engineers in their VR design chambers discussing the engine design, they look at the car and someone asks, how to change the chain, since it is on the back of the engine. The lead engineer steps in and says "Well, you simply remove the car" (clicks a button and the car is gone) "... and then you remove the transmission" (clicks another button and the transmission is gone) "... and there you go ... easy, right?".
I've seen plenty of dumb design choices on cars, but Audi takes the cake. They're basically designed so that a normal person can't work on them anymore.
I'm American and I've been driving a VW Alltrack for 6 years and 120,000 miles. I do all oil and fluid changes and replace consumables by myself at my garage. Not a single issue so far. This car is a joy to be in and drive unlike all the Toyotas I had before.
German car manufacturers have been lobbying the EU to make *any* self repairs illegal for about a decade. Last I heard, the EU are to introduce this as law.
@@conorstewart2214 it's a design flaw, you can't stop capillary action, but you could redesign to prevent the fluids from reaching the wires, but most of those wires are there because the sensors or what have you need to be there, so fundamentally it's a tricky problem.
I've only done minor maintenance on my 90's Toyota. Had no idea how spoiled I was because almost everything was easy to reach and often conveniently labeled.
Same with my 98 Galant and 2000 Pajero Pinin Mitsubishi's . In the other end , my hydro-pneumatic Citroen's are more challenging , but not at this levels ...
The green car with sliding down door is a 1989-91 BMW Z1. The door slid into a pocket between the sideskirt and inner paneling. The outside shell "pops off" to gain access to the entire working mechanisms. You can adjust the door tracking by using the belt tensioner very easily.
I’m a 21+year shop foreman for a German car line. The reason the timing drive is in the rear of the engines is not to mess with technicians. It’s not to hurt us or fu@k us, it’s because European pedestrians can’t seem to figure out how to keep themselves from being run over by vehicles. Thus pedestrian protection laws were passed in Germany, and I think the entire EU, that required all different kinds of fairly radical changes to vehicles to help lessen the impact and likelihood of serious injury or death when a pedestrian is hit by a car. Bumper heights, bumper shapes, bumper materials, pyrotechnic hood hinges, and so on were all innovations/changes brought on by these new laws. But the part of the law that caused the timing drive to move to the rear of the engine was the requirement for a certain amount of clearance between the underside of the hood and the top of anything hard beneath it. That amount of clearance was required by law to allow the hood to compress as a human body landed on it thus cushioning the blow and lessening the peak forces and reducing injury. My understanding is the manufacturers basically hard carte blanche when it came to how they went about achieving the requirements set forth by the law. The cheapest and easiest thing to do is just make the whole front of the car taller. But that’s obviously bad for aerodynamics and styling. Adding pyrotechnic hood hinges which popped the hood up upon impact with a pedestrian helped, but as the hood must remain solidly attached at the front and the hinges are at the rear, raising the hood at the rear did little to the clearance at the front of the hood. They could chose to lower the engine in the vehicle but it should be self obvious as to why there’s limits with that one. As the highest points on most all engines is the timing drive, and there’s not much that can be done to lessen that height, engineers had no choice but to move the timing drive to the rear of the engine. By doing this and having the deployable hinges, the manufacturers were able to meet the legal requirements. To be clear engineers do not hate techs. They don’t know us and they have to know us to hate us. They have their set of goals they must achieve, unfortunately technicians and their ease of access is not in that list. Contrary to popular belief, the engineers don’t hate us, they just don’t think about us at all. Or if they do it’s at the very end after every other goal has been achieved and at that point there’s not much they can do to help us. That camera on the dash of the E class is really there because of the full level 3 autonomous driving tech the car has. The camera is there to make sure the driver is still pay attention. There’s additional cameras hidden in the instrument cluster screen to track eye movement again for the level 3 autonomy tech. Literally could not agree more with the statement of if you see, hear, feel, or smell something wrong take it to the dealer. Good video overall! Nice to see some real techs talk some real truths about German cars.
>pedestrians are stupid >let's make it car owners' problem >bring in a bunch of politicians that have no idea what they're talking about, pass new laws that are largely ineffective and make everyone's life worse from top to bottom The culture and language may change, but politics is always the same.
counter point: every time I've had a vehicle to the dealer in the last 25 years, it hasn't been fixed properly. granted, I don't drive german vehicles.
As a German Engineer i can explain the complexity :) People want MOAR POWAR but the car cannot be too big. Especially in cities we usually dont have that amount of space available compared to a country that was founded later than most of our breweries XD In America there are wide roads for big trucks and huge parking space. Additionally your gas is about as expensive as our tap water. So we have to build efficient and effective engines with a very limited space. This can only be done by "overengineering" the engine.
As a Russo-German Engineer, you are Wrong! Its the ECONOMY and POLUTION Rea 9:53 son! And it works! And "founded later"? Hast du im Geschichtsunterricht geschwänzt oder was? 😂

Mitigation is an action taken to help prevent worse things from happening. E.g. storm water drains help mitigate potential flooding. Migration is when something moves elsewhere. The oil in the video is wicking up the wires via capillary action and migrating around the engine bay. To help mitigate damage caused by wicking like this you usually need to either change the size of the capillary tube or to change the surface to help prevent surface tension from building up.
That oil in the wiring... I had that in my year 2000 W203 C-class. Oil went from cam solenoid all the way into the Engine control module through the wires... I sprayed the ECM clean, covered it up again, replaced wires, bought the extra wiring harness fix as per TSB. I'm not even surprised Mercedes still has that issue 20 years later. lol
I have another post about this, but every GM product I've had has had, not large oil leaks, but just random small ones that add up over time to a healthy layer of oil and grease over the entire bottom half of the engine. I feel like I'd be screwed on every one of these vehicles if the wiring harnesses on them were prone to oil migration.
Not only leaving the timing chain at the back, it does not help when they decide to use narrower timing chain to ensure less friction and increase fuel efficiency. I’m glad my 2012 BMW E90 325i MSport has not given me any problem for the last 12 years. Only changed 2 ignition coils and recently, the shock mounts which is needed after 12 years.
Can relate to engineers not considering maintenance on machinery. Im a chairlift mechanic... They dont consider fixing/servicing anything and sometimes you gotta fix stuff that is 60 feet off the ground 😮
@@TheJaksserHe is not wrong. The headlight assembly was independently designed by GE. The design was ultimately rejected by BMW for square-ish, more fitting shape. Which is why they ended up on the Viper.
Yeah, plus probably also part of system that monitors for the driver falling asleep. They'll have just given it selfie mode as an extra thing to do because it might sell an extra couple of cars for no financial input.

01:42 Fake exhaust saves pennies on the BOM and exhaust is quieter when pointed away from any mics or ears, also reduces exhaust gunk on the bumper, all things your typical Audi customer cares about
16:20 Electronics tech here: The engine getting into the wiring harness? The word is 'migrate', not 'mitigate'.Once you've fixed whatever's causing the oil to leak into the harness, you *can* actually clean up connectors that've gotten oil into them though, the trick is to wash out the oil with a soak of isopropyl alcohol, repeating until it's clean, then spray them with contact-cleaner.
The SQ5 is a simple one. It's a diesel and it's better to dump that soot on the ground than on the car behind. In Europe you'll see LOTS of diesels with exhausts than point down and the gas versions point straight out.
well People like the visual of having "bag pipes" like that, but Laws are Laws, so you have the actual Exaust going down, with the Fakes for the Visual. And honestly who is going close enough to see them actually beeing fake?
About the scratching issue, I've bought a car with the front windows (especially driver's side) scratched all over, but all in straight lines up and down, on the exterior. The former owner's husband runs a construction company, so even though they did not necessarily take the car onto construction sites, there was always some dust, sand and other grit that would find its way onto the glass and was pushed against it by the seals.
I just wanna say with the pothole clip. I've had it happen to me where you've been driving a particular road, day in , day out for months, possibly years. And then one day it has a huge pothole. And you're just not ready for it, until it's too late. 😅
8:22 For an engineer that thinks about serviceability, he/she would have indented the heat shield to allow the bolt to come out, provided there's clearance behind.
Living in Germany and wrenching with buddies, I feel your pain so so much. As soon as someone with a local manufacturer needs stuff done, schedule becomes unbelievably busy.
And various monowipers go way WAY back. I don't know when Mercedes first had them, but I remember Subaru owners claiming the XT was the first car with one, back in the mid-80s, and that was already at least seventy years late.
Great video. Smiling and laughing the whole time. Keep Bob in the commercials and I’ll actually watch like I did this time. This is some of the best stuff on UA-cam.

The oil in the wiring harness is usually not a problem for the connected components such as the control unit or the throttle valve or other actuators. Only the lambda sensors do not speak well of it and have to be replaced. The remaining actors can be cleaned up and that's it. Of course, the source of the oil ingress, namely the leaking magnets of the camshaft adjustment, is replaced and a special oil-stop cable set is used to be on the safe side. This is sufficient in 99% of cases.
@@Havok135 EV has its place given the current state of the technology and more importantly the infrastructure to support it. Sadly the EV mandates we are seeing don't care about any of those things. So we are seeing the forced premature adoption of a technology that isn't ready and will only ultimately hurt its chances of being adopted naturally further down the line. It's only the dinosaurs who are forcing this tech down the markets throat in some hope of "helping the environment before we all die in 20 years" because that was what was drilled into their heads 20+ years ago already.

As for the problem with oil in the wiring harness on a lot of mercedes models, it caused by common fault of the hydraulic controlled variable valve timing. oil pushes its way through the connector to the connected cable, which then makes its way to the ecu, this happens because the fine strands in the flexible cables act like a wick of a candle/zippo. to prevent this before the harness is contaminated, you can either buy oil stop extensions ("Ölstoppkabel") or you cut the cables and reconnect them by soldering to achieve the same result. the solder, if applied correctly, stops the capillary effect of the flexible cables. If you understand german and are interested in mercedes specific mechanic content, I recommend the channel "Motoren Zimmer", its a channel by an owner/mechanic of a mercedes exclusive garage, where you can learn a lot about technical details on mercedes cars and their gas/petrol engines.
The potholes in Western NY in the spring will seriously reach out and drag you in. I have absofuckinglutely messed up a couple of cars like that. And they’re just unavoidable in certain places.
That built in selfie cam actually makes sense, the number of idiots I see taking selfies while driving every day is shocking. Sometimes you can tell with some certainty that they're using their phones while they're barreling at you because they're looking down and not at the road. But it's much more obvious when they're taking a selfie. It's infuriating how little self control people have. Just remembered a time last year when I was walking at night, and a girl in a new white jeep on her phone absent mindedly drove up onto the sidewalk right in front of me, hit a building, sat there taking selfies, then nearly backed into me and kept driving while looking at her phone. At no point did she look up from her phone, even when she *hit a building*.
We have mandatory yearly inspections in some US states. That doesn't really solve the problem. You're more likely to discover the problem. But, you've still got one!
@@notmirelnam248 it's easy to tell which states don't do inspections, the road's, car parks, drive throughs, have a lot of oil drips everywhere, especially at traffic lights.
Having lived in both, I don't see much difference. There's no obvious cut-off from state to state. The inspections mostly function like a "compulsory product" that you can't not buy. Nobody can get their car repaired because the shops are full to bursting with inspections on 2 year-old Muranos. I assume collusion between repair shops and government to set up a minimum customer base. It's a guaranteed extra chore for me to have to do on every vehicle and I am plenty capable checking my own vehicle without making an appointment or wasting half a day driving from shop to shop to see if they can fit me in. I love doing work that I don't get paid for. Not. Taking a few hours out a work day makes my employer happy too.
@@ajkulac9895 My point is that nobody can get their cars fixed when the shops are busy inspecting mechanically perfect cars. Inspecting them takes time away from repairing others and there's a labor shortage. Additionally, my dad would still be driving his craptastic '07 Chevy truck if it didn't cost a fortune every year to make the check engine light go away EVERY FREAKIN' YEAR! The truck worked fine, but had inconsistent misfires that none of the fixes ever solved. You could drive it like that for years and never find out if it was an O2 sensor, a grounding issue, a fuel injection issue, a crank sensor, a map sensor, or anything else. It would drive poorly for longer than most other cars drive at all. It became cost prohibitive to keep it legal, so its life got cut short, necessitating a completely different vehicle (and all of the mining and manufacturing required to produce it). How's that for saving the environment? Jackasses.
For it to build up that bad you would probably have to not wash your car for 2 months or something. Have an ecu tuned diesel car with a straight pointing exhaust that straight up leaves black clouds when you floor it but I've never had the soot build up enough to be even visible.

The mono wiper is amazing and really works at higher speeds without lifting off the glass, and it wipes more of the glass area than most cars with dual wipers. The 3 Mercedes that got it are the r129 SL (mine) the w124 e class featured, and the 190e
3 Tings for clearification. 1. the timing chain in the back is because of üpedestrian safety regulations you need a specific distanc between the engine and the hood. But when you want to drop the front for a better design the little hub from the timing gears is in the way so they put the timing chain in the back. (stil hate it) 2.The selfiecamera on the mercedes is as far as i know for the driver sleep detection system and it just is a little extra the programmed so the infotaimant sytem has access to it. 3. The mercedes 1 blade wiper is a really reliable system you just need to open it after 20 years, because the grease dries out and you need to relube it to function perfectly.

We also have the TÜV that your Car needs to pass, while i think something similar exists in some States, a lot of States don't have such a requirement
I’m a proponent of passing a regulation that requires, as the final step before a vehicle can be certified, that the engineers must preform 10 service and repair tasks assigned by a panel of service technicians, and complete them in book time. If they fail the whole design must be scrapped and company start over from a clean sheet. This will force them to either make them more serviceable, or more likely force them to have more responsible book times.
The exhaust tips is for insurance reasons, this way if you're rear ended there's a chance the exhaust system survives. This is especially true for rear engine cars (911). Not having the actual exhaust protrude gives you a chance at reducing costs of repair this is especially true in cases of fender benders where it would suck to have to replace the entire or part of the exhaust system because you got rear ended and the exhaust is damaged.
These videos prove to me what I've been thinking about a lot lately, newer cars are becoming overly complex, and difficult to maintain. I'm not a mechanic. I'm a lube tech. But I'm good with my hands and I prefer to do my own vehicles work as it's done exactly how I want it done. And I can redo things if necessary because I fully understand what I did. But these cars are the kind where u need the money to afford them and to pay somebody to maintain them. I enjoy working on my car. These types of things would literally take all the joy out of it and make it a job again.
The SQ5 with the fake exhaust is a diesel . During regeneration of the DPF it gets extremely hot (up to 800 degrees Celsius) . To not melt the rear fender, the exhaust is ending to the ground..
@@jaskajokunen3716 yes it used to be like that earlier . But starting from Euro 4 Diesel with DPF, you don’t have that amount of soot coming out the exhaust anymore
Regarding the oil making it`s way through the wiring harness into the engine computer, I work at a DAF dealership (Kenworth and Peterbilt`s european cousin) where I take care of both invoicing and warranty claims, and we had a similar case on a truck not too long ago, where there was a low oil pressure warning, and when the tech went to check it out, he found the sensor was dead and there was a liquid in the connector and harness, and by following the trace of said fluid, he found that one of the high pressure diesel unit pumps was leaking through it`s connector into the harness, and every other componant connected into the same harness was full of diesel, including the engine computer. Luckily for the customer it was a used truck that was under a full warranty, because we ended up replacing the defective pump, upper engine harness, the engine computer, the oil pressure sensor, the exhaust back pressure sensor, and another sensor that was connected to that same harness that I`m now blanking on. Although rare, we have come across other similar situations where oil or coolant make it into a harness before, so this is not specificly a german car thing, though it`s crazy to me that this is even a thing thay can happen As for programming the PCI once replaced, it also has to be done using the OEM software, because the diag software has to download the vehicle`s vin specific engine management software from DAF`s servers before installing it to the PCI, which also means that if you`re going to replace a PCI (or most other control modules), whether it`s on the road or in the shop, you either need an active internet connection to be able to flash the ECU, or you`d better be sure to download the software to your computer beforehand. Also, because the control software is VIN specific, if you decide to plug the module into another vehicle with the intention of programming it so that when you leave for an on-site repair all that you`d have to do is install the module and turn the key, you`d be SOL because you`d only be able to install the software that belongs to the vehicle you`d be connecting to, meaning that when you`d arrive on site to install the module, at best you`d get errors on the dash and mismatched VIN fault codes, and at worst it wouldn`t work ar all
The engineering for the roll down doors on the Z1 is pretty cool if you're into how things work. It's all run on a single belt, just like a serpentine belt. Apparently even though they are "long lasting" belts, BMW warned owners not to "abuse" the roll down door function too much, because to replace the belt is something like 10-15 hours labor.
0:41 That particular engine is actually from an S4. Audi wanted to use the A6's engine in that, but it wouldn't fit unless they "turn it around". Hence why the chains ended up at the firewall-side of the engine. 2:10 The SQ5 is a diesel. It's common for diesels to have the exhaust tip pointed down.
There may be reasons for everything, however, 90% of the jobs on a Honda, will take less than half the time as the same job on a German car. I may drive Toyotas now primarily, but when a buddy brings me their Honda to work on it is like coming home. All my tools, wrenches, and extensions fit where they should easily. Bonus: No triple squares.

The oil in Dave's shop is migrating down the wires (bad). If it's migrating, you need to mitigate the problem.

I was really into air cooled VWs in the ‘80s and got a job at a VW/Porsche shop. One day I was told to replace the water pump on a 928, so I looked in the book… “9.5hrs” and about 20 minutes of it was actually replacing the, timing belt driven, water pump.
In engineering class here in Germany our Professor always told us of the German tractor company Lenz. They've built tractors that needed no maintenance and would run forever. The hot bulp engines could be operated by an illetarete peasant and ran on everything from lard to heavy fuel oil. They sold them until everyone who could afford one had one. And then they went bankrupt. The more complex a car is the more expensive it is to fix, those cars must survive nor more 10 years or 250.000 km, leave a good impression and then fail. It's a sad reality.
Is the schematics for the engine still available
@@tienming6174 You dont want to drive that engine
@@tienming6174 If you're interested in hot bulp engines I'd recommend you google them, but they're no longer in use since they have a very low compression and therefore low efficiency.

Used German automobiles are weapons of mass economic destruction.
Yea I mean it's just basic business... if you make something that lasts forever you're eliminating tons of future customers and you're now forced to compete with yourself to stay alive.
To mitigate is to make less severe... to migrate is to move (or in the case of oil to flow) from one place to another.

'I heard you like timing chains, so we got you a timing chain for your timing chain' -Xzibit, probably.
So, I'd like to explain something - coming from an engineer. We don't want to design stuff that makes it hard to work on. We are made to by others. I'm a process electrical engineer, which means I design the automation systems in manufacturing facilities. I'd love to make every control panel have lots of room for technicians to work in, because that makes it easier on me for design and implementation as well.
But what happens is the higher ups say - well, cost of 50 48" panels is xxx more than 50 36" panels, so just slam everything into those smaller panels. Or We need x (which usually takes up 12" of space with room to wire/access) to fit in this 8" space, and no we can't change anything else because there's no room, just make it fit.
That is the reason you get those bolts in odd places that are hard to reach, or those terminal blocks with only 1/2" of finger room to wire them and so on.
We don't want to make stuff that way, but we don't usually have the final say. Everyone blames the engineer, trust us, we know, we told the project managers and higher ups about it but were told to do it anyways because they don't care.
yup I'm a mechanic and I defend yall all the time... I know you guys are way too smart to not notice obvious serviceability issues during the design process, it's the pencil pushers always trying to save a buck making yall look bad especially in the Auto Industry. It has gotten so bad I have literally seen repair instructions written by BMW that call for you to cut away pieces of plastic or just straight up break trim pieces to repair something else 🤣🤣🤣 I know for a fact no engineer would willingly sign off on that
Here in Poland BMWs are famous (among some people) for NEVER having rust problems, but servicing is a financial NIGHTMARE or even a DAYMARE

The mono wiper on the older MBs in AMAZING. I'm akways in awe how much of the window it actually reaches, arguably more than the more common dual wiper setups. And I'm positively surprised that it does not seem to break. Very well designed mechanism inside of this "turtle shell" it sits in.
I love them too, I have a couple W202's that have them. The only real maintenance they require is to be re-greased which isn't hard by any means. The bigger issue is the wiper motor has a worm screw that rotates a plastic shaft, which will make the wiper "pause" in the middle of the window when it starts to fail. Although considering the cars are well over 20 years old, I wouldn't say it's a "big" issue if they are just starting to fail. Just replace them with OEM, a cheap aftermarket failed on me within a couple of months.
I had to rebuild one because of parts availability. I watched a UA-cam video and got what new parts we could but it worked in the end. Pretty cool system and a learning experience
because thats when mercedes were built to last
The majority of sedans aren't that bad. The suv's on the other hand are complete garbage
My Father still uses daily his '99 E220 CDi (auto) , that wiper arm never gave any problem . My 2 Citroen BX also have a monoarm , but no need for the cinematic mechanism has the windshield in high enough , but the sprayers are in the arm and move with the blade (the tube passes in the middle of the axe of the Arm ) , so it never runs dry , and you don't have the sprinklers on the hood for aesthetics .
Bruh I love these two. Everyone that has shown up on Real Mechanics have really been gems and have provided me with valuable knowledge and I appreciate all of you helping me grow.
16:53 What happens is that oils have extremely high surface tension. They are engineered this way to get into small places and cling to and coat the wear surfaces. Pretty much every wire in a car is stranded wire, there are almost zero solid core wires ever found in a car. Once the oil gets into a connector it will cling to all the individual strands inside the wire. Because of the very high surface tension it literally will be sucked along by capillary forces through that tiny space between all the strands. The capillary action will just continue to flow that oil drop by drop through the wires until they find something they cannot get around (a computer, connector, etc) and sometimes even drip out onto other electrical components. Any places that are really hot it'll turn into a gummy shellac like coating. And as most wiring gaskets are not made from oil safe materials the solvents that remove carbon buildup from the engine will actually start to dissolve components in the plastics making them very brittle and seals fail.
Yea I was going to say, Mitigate is the wrong word they used.
But what is causing the oils to get into the wires in the first place?
Why does oil damage electrical components?
@@mattbritton6222 So it impacts them in a few ways: One engine motor oil has solvents and detergents in it. Now not all components will have issues with this, but capacitors are usually pretty vulnerable to being comprised by engine oil. There are capacitors that do not have just a thin seal, but they cost more, so the cheap ones are typically whats found. Once oil wicks into them they loose their ability to function within spec.
Two, it will eat away certain seals and can damage masking on boards. This can lead to water entering past those seals and causing more problems. Masking issues will cause potential shorts in the layers on a PCB.
Three, clean oil is not much of a problem for electrically, its usually not conductive. However dirty oil is. A lot of impurities in old engine oil make is mildly conductive. So while its rare to directly cause shorts, it can introduce a general capacitance and screw up higher speed digital signals.
Four, Oil can tend to turn into a thick paste that impedes airflow so systems like the ECU that may need good cooling might just cook themselves when coated with oil residue.
To be honest if you had a high quality petroleum oil without the additives (e.g. Mineral Oil) it would generally be fine to submerge all your electrical components in it. It's really just that things designed to remove carbon build up from engines also are not great for electronics.
I wonder why this is more common on German vehicles? I mean, I've had have valve cover gasket leaks on every GM vehicle I've ever owned, not fast (like enough to keep things visibly oily and greasy but not quite drip on the ground). I bothered to measure it on one vehicle I had and found it was 1/4 of a quart per 10,000 miles... which is low, but over many miles it adds up to multiple quarts run out over the bottom half of that engine, it was quite greasy on all these vehicles. I'm just saying if it wsa guaranteed that oil worked it's way up, I think I would have been screwed on all these vehicles.
My Chevy Cruze started really pissing out oil, I fixed an oil line myself, then got the valve cover and valve cover gasket replaced when they started leaking like a sieve (it began leaking fast enough I brought a jug of oil with me and was topping it up every time I stopped. No I didn't let it run low, and I got it fixed ASAP but the shop was booked up so that took about a week.) I replaced the parts on these that all act up at about 140,000 miles so it's been running nice and holding it's fluids in fine since. Anyway, with all that oil dumping out I didn't have it run up my wiring on there either.

I saw that glass scratch issue once. Found the problem pretty quick, the customer had "fixed" their door previously(they'd unscrewed the plate for the interior door handle to fix a hook). Trouble is, when they put it back together, they just used whatever screw they had lying around that fit. And they used one that was WAY too long.
And then they were surprised when it scratched up their window.

16:33 Propagate, not mitigate. This is capillary action, where a fluid creeps along, even against gravity. The quick fix is filling the harness with oil resistant silicone or RTV at the connecter that fails. The Golf Mk4 has the same issue with the harness from the water temp sensor on the expansion tank. Starts to leak, coolant seeps through the harness into the computer and fries it.
I get why coolant is an issue in electrical components, but what does oil do?
@@mattbritton6222 Any fluid getting into an electrical system will cause issues. It either gets in between connections (breaking the connection), traps heat and overheat the components, or cause other issues.
Computer parts are very sensitive and delicate. Even if a fluid is not conductive, it will cause major problems.

I am German and I agree. I drove an Audi and you had to bring the car to the mechanics to change a light bulb in your head lights, that is really frustrating. Or a 5 cent light bulb in your dash breaks and you would have to remove the middle console and the dash to change it, that is simply a stupid design. Looks great though, but as soon as you start repairing stuff, it becomes a nightmare. Imagine the engineers in their VR design chambers discussing the engine design, they look at the car and someone asks, how to change the chain, since it is on the back of the engine. The lead engineer steps in and says "Well, you simply remove the car" (clicks a button and the car is gone) "... and then you remove the transmission" (clicks another button and the transmission is gone) "... and there you go ... easy, right?".
My old one not, a6 bj.99 :)
I've seen plenty of dumb design choices on cars, but Audi takes the cake. They're basically designed so that a normal person can't work on them anymore.

@@conorstewart2214 it's a design flaw, you can't stop capillary action, but you could redesign to prevent the fluids from reaching the wires, but most of those wires are there because the sensors or what have you need to be there, so fundamentally it's a tricky problem.

I’m a 21+year shop foreman for a German car line. The reason the timing drive is in the rear of the engines is not to mess with technicians. It’s not to hurt us or fu@k us, it’s because European pedestrians can’t seem to figure out how to keep themselves from being run over by vehicles. Thus pedestrian protection laws were passed in Germany, and I think the entire EU, that required all different kinds of fairly radical changes to vehicles to help lessen the impact and likelihood of serious injury or death when a pedestrian is hit by a car. Bumper heights, bumper shapes, bumper materials, pyrotechnic hood hinges, and so on were all innovations/changes brought on by these new laws. But the part of the law that caused the timing drive to move to the rear of the engine was the requirement for a certain amount of clearance between the underside of the hood and the top of anything hard beneath it. That amount of clearance was required by law to allow the hood to compress as a human body landed on it thus cushioning the blow and lessening the peak forces and reducing injury. My understanding is the manufacturers basically hard carte blanche when it came to how they went about achieving the requirements set forth by the law. The cheapest and easiest thing to do is just make the whole front of the car taller. But that’s obviously bad for aerodynamics and styling. Adding pyrotechnic hood hinges which popped the hood up upon impact with a pedestrian helped, but as the hood must remain solidly attached at the front and the hinges are at the rear, raising the hood at the rear did little to the clearance at the front of the hood. They could chose to lower the engine in the vehicle but it should be self obvious as to why there’s limits with that one. As the highest points on most all engines is the timing drive, and there’s not much that can be done to lessen that height, engineers had no choice but to move the timing drive to the rear of the engine. By doing this and having the deployable hinges, the manufacturers were able to meet the legal requirements. To be clear engineers do not hate techs. They don’t know us and they have to know us to hate us. They have their set of goals they must achieve, unfortunately technicians and their ease of access is not in that list. Contrary to popular belief, the engineers don’t hate us, they just don’t think about us at all. Or if they do it’s at the very end after every other goal has been achieved and at that point there’s not much they can do to help us.
That camera on the dash of the E class is really there because of the full level 3 autonomous driving tech the car has. The camera is there to make sure the driver is still pay attention.

In America there are wide roads for big trucks and huge parking space. Additionally your gas is about as expensive as our tap water.
So we have to build efficient and effective engines with a very limited space. This can only be done by "overengineering" the engine.

Mitigation is an action taken to help prevent worse things from happening. E.g. storm water drains help mitigate potential flooding.
Migration is when something moves elsewhere. The oil in the video is wicking up the wires via capillary action and migrating around the engine bay. To help mitigate damage caused by wicking like this you usually need to either change the size of the capillary tube or to change the surface to help prevent surface tension from building up.
Glad I'm not the only one who caught that. I guess there is some hope for our education system... Though I shouldn't get my hopes up.
That oil in the wiring... I had that in my year 2000 W203 C-class. Oil went from cam solenoid all the way into the Engine control module through the wires...
I sprayed the ECM clean, covered it up again, replaced wires, bought the extra wiring harness fix as per TSB.
I'm not even surprised Mercedes still has that issue 20 years later. lol
I have another post about this, but every GM product I've had has had, not large oil leaks, but just random small ones that add up over time to a healthy layer of oil and grease over the entire bottom half of the engine. I feel like I'd be screwed on every one of these vehicles if the wiring harnesses on them were prone to oil migration.
Not only leaving the timing chain at the back, it does not help when they decide to use narrower timing chain to ensure less friction and increase fuel efficiency.

But we can agree that it is (probably) a fact, but not at all a 'fun' one.
The BMW with the roll down doors is a Z1 btw ✌
While I do agree that it’s a bit odd, my honest guess was that dash camera is mainly for video calls when not in motion and also security.

16:20 Electronics tech here: The engine getting into the wiring harness? The word is 'migrate', not 'mitigate'.Once you've fixed whatever's causing the oil to leak into the harness, you *can* actually clean up connectors that've gotten oil into them though, the trick is to wash out the oil with a soak of isopropyl alcohol, repeating until it's clean, then spray them with contact-cleaner.
The SQ5 is a simple one. It's a diesel and it's better to dump that soot on the ground than on the car behind. In Europe you'll see LOTS of diesels with exhausts than point down and the gas versions point straight out.
it's mandatory in Germany to have it like that if it's a diesel.
the don't use fake ones lol
@@hughmann7485 well they look good (Tastes may vary...)
well People like the visual of having "bag pipes" like that, but Laws are Laws, so you have the actual Exaust going down, with the Fakes for the Visual. And honestly who is going close enough to see them actually beeing fake?
It's Audi thing, magically bmw has normal pipes on diesels while Merc is mixed bag.
About the scratching issue, I've bought a car with the front windows (especially driver's side) scratched all over, but all in straight lines up and down, on the exterior.
The former owner's husband runs a construction company, so even though they did not necessarily take the car onto construction sites, there was always some dust, sand and other grit that would find its way onto the glass and was pushed against it by the seals.
I spend a lot of time on dirt roads, some pretty bad, and have that, too. That dust and sand can get anywhere
All that extra tech in a car is just more stuff to break down.
Fun fact about the mono-wiper: It covers more than 80% of the windscreen's surface.
Juan is the real deal. Super humble and super clever.

I just wanna say with the pothole clip. I've had it happen to me where you've been driving a particular road, day in , day out for months, possibly years. And then one day it has a huge pothole. And you're just not ready for it, until it's too late. 😅
That bang just hurts your soul because who knows the kind of damage it just did to your "baby. "
8:22 For an engineer that thinks about serviceability, he/she would have indented the heat shield to allow the bolt to come out, provided there's clearance behind.
Living in Germany and wrenching with buddies, I feel your pain so so much. As soon as someone with a local manufacturer needs stuff done, schedule becomes unbelievably busy.
Glass guy here, that mono wiper is super cool, but super awful when doing the windshield.
And various monowipers go way WAY back. I don't know when Mercedes first had them, but I remember Subaru owners claiming the XT was the first car with one, back in the mid-80s, and that was already at least seventy years late.

I think you mean the oil will “migrate” up the wires. “Mitigate” means to make less severe, which is exactly the opposite of what is happening.
We've all been there. Brain gets locked on a wrong but similar word and won't let go.
They are mechanics, they don't know English very well.
Thank you - I was wondering if there was an alternate use of the word that I was unaware of 😂

So much electronics in a car freak me out - my mechanic gave me a Audi 80 from 1981 whilst my car was in his shop. It basically had three buttons in it. The best car I´ve ever drven.
15 years later and I´m still dreaming of that car.
The oil in the wiring harness is usually not a problem for the connected components such as the control unit or the throttle valve or other actuators. Only the lambda sensors do not speak well of it and have to be replaced. The remaining actors can be cleaned up and that's it. Of course, the source of the oil ingress, namely the leaking magnets of the camshaft adjustment, is replaced and a special oil-stop cable set is used to be on the safe side. This is sufficient in 99% of cases.
That's why I can't wait to see camless valvetrains becoming standard, no more complications with valvetrains and no power sapped.
Free valve has so much potential that could be lost if the rest of the world continues to try and force EV adoption.
Camless doesn’t mean

Sadly the EV mandates we are seeing don't care about any of those things. So we are seeing the forced premature adoption of a technology that isn't ready and will only ultimately hurt its chances of being adopted naturally further down the line.
It's only the dinosaurs who are forcing this tech down the markets throat in some hope of "helping the environment before we all die in 20 years" because that was what was drilled into their heads 20+ years ago already.

I can’t believe how complex German cars have become, especially with how simple old vws like mine are
With old beetles all you had to worry about was the fan belt. Which you could hot swap if you were skilled enough lol.
Old BMWs are still pretty simple, too. Up until around 2006 or so, still fairly easier but they started getting more complex with electric water pumps and electric power steering etc
Everything is complex, now. Though the Germans do seem to make things a little more complicated than the rest, and charge like a rhino for parts.
I work for BMW and tons of new engines utilize port and direct injection to improve emissions... also my shop foreman told me after he went to training that apparently some of the new generation of cars are gonna have regenerative struts... that is F1 tech they are slamming into street cars 🤣
@@evelynsahoe8896 regen struts?? that's awesome, didn't know that was coming so soon, but it makes sense because it's a lot of lost energy on the road.
As for the problem with oil in the wiring harness on a lot of mercedes models, it caused by common fault of the hydraulic controlled variable valve timing. oil pushes its way through the connector to the connected cable, which then makes its way to the ecu, this happens because the fine strands in the flexible cables act like a wick of a candle/zippo. to prevent this before the harness is contaminated, you can either buy oil stop extensions ("Ölstoppkabel") or you cut the cables and reconnect them by soldering to achieve the same result. the solder, if applied correctly, stops the capillary effect of the flexible cables. If you understand german and are interested in mercedes specific mechanic content, I recommend the channel "Motoren Zimmer", its a channel by an owner/mechanic of a mercedes exclusive garage, where you can learn a lot about technical details on mercedes cars and their gas/petrol engines.

Hearing them say Mitigate when they mean to say Migrate is amusing. Mitigate: Prevent Migrate: Move.
The potholes in Western NY in the spring will seriously reach out and drag you in. I have absofuckinglutely messed up a couple of cars like that. And they’re just unavoidable in certain places.
That built in selfie cam actually makes sense, the number of idiots I see taking selfies while driving every day is shocking. Sometimes you can tell with some certainty that they're using their phones while they're barreling at you because they're looking down and not at the road. But it's much more obvious when they're taking a selfie. It's infuriating how little self control people have. Just remembered a time last year when I was walking at night, and a girl in a new white jeep on her phone absent mindedly drove up onto the sidewalk right in front of me, hit a building, sat there taking selfies, then nearly backed into me and kept driving while looking at her phone. At no point did she look up from her phone, even when she *hit a building*.
That's when you report their plate number to police for attempted vehicular manslaughter
Oh, I see you met my ex.
Germany has compulsory roadworthiness tests which isn't a thing in the US (well everywhere) so cars get fixed sooner.
We have mandatory yearly inspections in some US states. That doesn't really solve the problem. You're more likely to discover the problem. But, you've still got one!
@@notmirelnam248 it's easy to tell which states don't do inspections, the road's, car parks, drive throughs, have a lot of oil drips everywhere, especially at traffic lights.
Having lived in both, I don't see much difference. There's no obvious cut-off from state to state. The inspections mostly function like a "compulsory product" that you can't not buy. Nobody can get their car repaired because the shops are full to bursting with inspections on 2 year-old Muranos. I assume collusion between repair shops and government to set up a minimum customer base.
It's a guaranteed extra chore for me to have to do on every vehicle and I am plenty capable checking my own vehicle without making an appointment or wasting half a day driving from shop to shop to see if they can fit me in. I love doing work that I don't get paid for. Not. Taking a few hours out a work day makes my employer happy too.
@@notmirelnam248 If you still got one you're not registering your car before you fix it, meaning you can't drive it on the road.
@@ajkulac9895 My point is that nobody can get their cars fixed when the shops are busy inspecting mechanically perfect cars. Inspecting them takes time away from repairing others and there's a labor shortage.
Additionally, my dad would still be driving his craptastic '07 Chevy truck if it didn't cost a fortune every year to make the check engine light go away EVERY FREAKIN' YEAR! The truck worked fine, but had inconsistent misfires that none of the fixes ever solved. You could drive it like that for years and never find out if it was an O2 sensor, a grounding issue, a fuel injection issue, a crank sensor, a map sensor, or anything else. It would drive poorly for longer than most other cars drive at all. It became cost prohibitive to keep it legal, so its life got cut short, necessitating a completely different vehicle (and all of the mining and manufacturing required to produce it). How's that for saving the environment? Jackasses.
The exhaust is pointing down on diesels to prevent soot buildup on rear bumber and having it look like a mess.
For it to build up that bad you would probably have to not wash your car for 2 months or something. Have an ecu tuned diesel car with a straight pointing exhaust that straight up leaves black clouds when you floor it but I've never had the soot build up enough to be even visible.
its actually because of german law. Diesels need their exhaust to point to the road to minimize airborn Diesel particles
@@sytricka3318 average joe here. i wash my car once a year at max. we get a lot of high winds coming from the south carrying sahara dust, and trying to clean the car without scratching it takes ages, so i just wait for the next rain nowadays

But yeah.. it still isnt fun. Im too cheap to spend 10$ going to a car wash but I also think car washes can be a bit too rough.
The mono wiper is amazing and really works at higher speeds without lifting off the glass, and it wipes more of the glass area than most cars with dual wipers. The 3 Mercedes that got it are the r129 SL (mine) the w124 e class featured, and the 190e

3 Tings for clearification.
1. the timing chain in the back is because of üpedestrian safety regulations you need a specific distanc between the engine and the hood. But when you want to drop the front for a better design the little hub from the timing gears is in the way so they put the timing chain in the back. (stil hate it)
2.The selfiecamera on the mercedes is as far as i know for the driver sleep detection system and it just is a little extra the programmed so the infotaimant sytem has access to it.
3. The mercedes 1 blade wiper is a really reliable system you just need to open it after 20 years, because the grease dries out and you need to relube it to function perfectly.
"Design for manufacture" and "design for service" are fundamental automotive engineering principles. "Overengineering" means never needs to be fixed or easy to fix. IMHO at least...
I've always heard that overengineered means using a needlessly complicated solution when simpler ones exist.
@@bf5175 I'm an engineer attempting humor mixed with a little seriousness. I'll try to stay in my lane in the future.
@@rajon25 Good effort, though to non-engineers, that definition would make them mad. "Well engineered" would mean never needing to be fixed/easy to fix. We're in short supply of well-engineered tech now cause everyone trying to make things cheaper and break faster so the company can make more money (planned obsolescence).
i find this perspectiv Interesting, as someone who lives in Germany and owns a German Car, i rarly ever have issues. But we also go and Service our Cars regularly, while i guess Americans just don't care? and hence stuff breaks. We also have the TÜV that your Car needs to pass, while i think something similar exists in some States, a lot of States don't have such a requirement
Overengineered means engineered at a higher level than what is requested, e.g. 2JZ engines that can withstand hundreds of HP more than stock.
I’m a proponent of passing a regulation that requires, as the final step before a vehicle can be certified, that the engineers must preform 10 service and repair tasks assigned by a panel of service technicians, and complete them in book time.
If they fail the whole design must be scrapped and company start over from a clean sheet.
This will force them to either make them more serviceable, or more likely force them to have more responsible book times.
Do garages have a problem with complicated repairs? They simply charge more, don't they?
Timing chain is a common failure on b7 audi a4
Just did one on a c7 A6 3.0 and will need to on my c7 S6 as well soon. Granted that's at 167k and 150k respectively but still a pita
The exhaust tips is for insurance reasons, this way if you're rear ended there's a chance the exhaust system survives. This is especially true for rear engine cars (911). Not having the actual exhaust protrude gives you a chance at reducing costs of repair this is especially true in cases of fender benders where it would suck to have to replace the entire or part of the exhaust system because you got rear ended and the exhaust is damaged.
These videos prove to me what I've been thinking about a lot lately, newer cars are becoming overly complex, and difficult to maintain. I'm not a mechanic. I'm a lube tech. But I'm good with my hands and I prefer to do my own vehicles work as it's done exactly how I want it done. And I can redo things if necessary because I fully understand what I did. But these cars are the kind where u need the money to afford them and to pay somebody to maintain them. I enjoy working on my car. These types of things would literally take all the joy out of it and make it a job again.
2:10 stick of truth!
The SQ5 with the fake exhaust is a diesel . During regeneration of the DPF it gets extremely hot (up to 800 degrees Celsius) . To not melt the rear fender, the exhaust is ending to the ground..
Doesnt it also help with not sooting up the bumper? 🤔
@@jaskajokunen3716 yes it used to be like that earlier . But starting from Euro 4 Diesel with DPF, you don’t have that amount of soot coming out the exhaust anymore

Brilliant Simplisafe ad, well done 😎
Regarding the oil making it`s way through the wiring harness into the engine computer, I work at a DAF dealership (Kenworth and Peterbilt`s european cousin) where I take care of both invoicing and warranty claims, and we had a similar case on a truck not too long ago, where there was a low oil pressure warning, and when the tech went to check it out, he found the sensor was dead and there was a liquid in the connector and harness, and by following the trace of said fluid, he found that one of the high pressure diesel unit pumps was leaking through it`s connector into the harness, and every other componant connected into the same harness was full of diesel, including the engine computer. Luckily for the customer it was a used truck that was under a full warranty, because we ended up replacing the defective pump, upper engine harness, the engine computer, the oil pressure sensor, the exhaust back pressure sensor, and another sensor that was connected to that same harness that I`m now blanking on. Although rare, we have come across other similar situations where oil or coolant make it into a harness before, so this is not specificly a german car thing, though it`s crazy to me that this is even a thing thay can happen
As for programming the PCI once replaced, it also has to be done using the OEM software, because the diag software has to download the vehicle`s vin specific engine management software from DAF`s servers before installing it to the PCI, which also means that if you`re going to replace a PCI (or most other control modules), whether it`s on the road or in the shop, you either need an active internet connection to be able to flash the ECU, or you`d better be sure to download the software to your computer beforehand. Also, because the control software is VIN specific, if you decide to plug the module into another vehicle with the intention of programming it so that when you leave for an on-site repair all that you`d have to do is install the module and turn the key, you`d be SOL because you`d only be able to install the software that belongs to the vehicle you`d be connecting to, meaning that when you`d arrive on site to install the module, at best you`d get errors on the dash and mismatched VIN fault codes, and at worst it wouldn`t work ar all
The engineering for the roll down doors on the Z1 is pretty cool if you're into how things work. It's all run on a single belt, just like a serpentine belt. Apparently even though they are "long lasting" belts, BMW warned owners not to "abuse" the roll down door function too much, because to replace the belt is something like 10-15 hours labor.

The SQ5 is a diesel. It's common for diesels to have the exhaust tip pointed down.
There may be reasons for everything, however, 90% of the jobs on a Honda, will take less than half the time as the same job on a German car.
